I'm playing with Go and run into something I'm unable to find in Google, although there is certainly something that exists:

I'm using the following struct:

type Syntax struct {
  name string
  extensions *regexp.Regexp
}

type Scanner struct {
  classifier * bayesian.Classifier
  save_file string
  name_to_syntax  map[string] *Syntax
  extensions_to_syntax  map[*regexp.Regexp] *Syntax
}

I'd like to perform the following using Go and I'm quoting ruby because it's how I'd do that using ruby:

test_regexpes = my_scanner.extensions_to_syntax.keys

My goal is to get an array of *regexp.Regexp .

Any idea on how to do that in a simple way ?

Thank you !
